Translation turntable mechanism 13 principle of work of aging tester 1:
When motor 1304 rotates, first synchronizing wheel 1308 of motor 1304 axle head drives the second synchronizing wheel 1311 to rotate by the first Timing Belt 1309, because the first rotating shaft about 1310 two ends are fixed with pivot arm 1305 upper plate and the second synchronizing wheel 1311, and pivot arm 1305 upper plate and pivot arm 1305 be fixing together with, therefore, when the second synchronizing wheel 1311 rotates, pivot arm 1305 follows rotating Vortex together.4th synchronizing wheel 1315 ' is fixed on the first tubular shaft 1312, and the first tubular shaft 1312 is fixed on rotating base 1302, and the 4th synchronizing wheel 1315 ' on the first tubular shaft 1312 is just actionless relative to rotating base 1302.
Because pivot arm 1305 rotates with the first tubular shaft 1312, in the second rotating shaft 1316 being fixed on pivot arm 1305 other end, the second tubular shaft 1317 rotates around the second rotating shaft 1316, and the 4th synchronizing wheel 1315 ' be fixed on the 3rd synchronizing wheel 1315 of the second tubular shaft 1317 and the first tubular shaft 1312 is linked up by the second Timing Belt 1314.If pivot arm 1305 turns clockwise, the 4th synchronizing wheel 1315 ' then on the first tubular shaft 1312 is just be rotated counterclockwise relative to pivot arm 1305, the 3rd synchronizing wheel 1315 on the second tubular shaft 1317 connected by the second Timing Belt 1314 is also rotated counterclockwise relative to pivot arm 1305, because translation turntable 1307 and the second tubular shaft 1317 are fixed together, therefore translation turntable 1307 is with the rotating Vortex simultaneously of the 3rd synchronizing wheel 1315 on the second tubular shaft 1317, and platform turntable is just rotated counterclockwise relative to pivot arm 1305.Translation turntable 1307 is while the axis of the first tubular shaft 1312 rotates, and translation turntable 1307 is self reverse rotation also.Aging loading plate 30 diameter phi D circle always can through the axis of the first tubular shaft 1312, and the cutting direction of aging loading plate 30 in the same direction always.Therefore by such movement locus, on aging loading plate 30 LED component 302 can successively below integrating sphere 121 port measure, and can ensure that the directivity of LED component 302 is consistent.
The present invention is relative to the benefit of prior art: by adopting special aging loading plate as the running carrier of LED component aging test between aging tester and aging cabinet, there is provided the tester of specialty once can carry out test job to multiple LED, and the ageing state of each LED can Real-Time Monitoring and control, not only increase the efficiency of detection, and cost is low, a large amount of function measuring test specimen can be completed.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
